IR Transmitter and Receiver

U2532B

Description

The IC U2532B is a complete IR-Transmitter-Receiver

IC according to the new IrDA 1.0 standard.

ASK-modulation is also possible. Only an external

PIN-photodiode and an infrared emitting diode with

current limiting resistor must be connected to the

corresponding pins. The amplifier with Schmitt-Trigger

formed output signal and the IR-driver need no further

external components. The IC allows data rates from

2.4 kbit/s to 115.2 kbit/s and up to 500 kHz for

ASK-modulation. Two different sensitivity modes, which

can be programmed by applying a “High” or “Low”

voltage at pin SC, ensure either an increase in

transmission distance or a bit error rate of 1E-9. An

internal AGC allows proper operation under EMI

conditions.
